Tax Pro PTIN at IRS.gov: Requirements, Renewal, and Penalties

Anyone paid to prepare a federal tax return needs a Preparer Tax Identification Number, and the core PTIN requirements and renewal rules are straightforward: apply online through the IRS, pay $18.75, and renew the number every year between mid-October and December 31.¹ The online application takes about 15 minutes and issues your number immediately. A paper option exists but takes roughly six weeks to process.²

Who Has to Have a PTIN

You need a PTIN if you’re paid to prepare, or help prepare, all or substantially all of a federal tax return, refund claim, or other IRS form. “Substantially all” means doing real substantive work on the return: filling out schedules, computing figures, or assembling the forms. Simple data entry of numbers someone else calculated doesn’t trigger the rule.³

The requirement reaches further than most people expect. It applies even if you never sign the return. Non-signing preparers, including interns whose work is reviewed and signed by a supervisor, still need their own PTIN.³ The one employee exception: if you prepare only your own employer’s return as part of your job, you don’t need one.

Enrolled agents need a PTIN in all cases. CPAs and attorneys need one only when they actually prepare returns for compensation; holding the credential alone doesn’t trigger the requirement.³ Volunteer preparers who take no pay are exempt. Your PTIN belongs to you personally. It cannot be shared, transferred, or used by anyone else. The underlying authority is Internal Revenue Code Section 6109, which requires every return prepared for compensation to carry the preparer’s identifying number.⁴

Getting Your PTIN the First Time

Most first-time applicants use the online PTIN account system. Fifteen minutes, start to finish.¹ Before you log in, have this in front of you:

Your Social Security Number or ITIN.
A personal mailing address and contact information.
Details from a prior-year tax return, which the system uses to verify your identity.
Your professional credential number if you have one: CPA license, enrolled agent card, or attorney bar ID.

Identity verification runs through ID.me. You’ll upload a photo of a government-issued ID (driver’s license, state ID, or passport) and take a selfie with a phone or webcam. An existing ID.me account from another government service will let you sign in with those credentials.⁵

Once you’re in, choose “Register for a PTIN.” The application asks background questions about your tax compliance history, including any felony convictions and outstanding tax debts.⁶ You’ll agree to the professional conduct standards in Treasury Department Circular 230, which governs how practitioners deal with the IRS.⁷

The final step is paying $18.75 by credit card, debit card, or electronic check. The fee is non-refundable. Once payment processes, your PTIN appears on screen, and you can begin preparing returns right away.¹

Paper Application

If you’d rather not use the online system, you can submit Form W-12 by mail. The tradeoff is real: about six weeks of processing time versus instant results online, plus you have to mail an original or notarized copy of your Social Security card together with a notarized copy of another government-issued photo ID.⁶ The fee is still $18.75. Applying by paper close to filing season can leave you unable to work.

Foreign Preparers Without an SSN

Foreign preparers who work on U.S. returns from outside the country can get a PTIN, but the paperwork is heavier. You’ll file Form W-12 together with Form 8946, the PTIN Supplemental Application for Foreign Persons Without a Social Security Number.³ You must not have and not be eligible for an SSN, must not be a U.S. citizen or permanent resident, and must have a foreign physical mailing address.

You’ll submit two current, unexpired, government-issued documents that together verify identity and foreign status. At least one must include your photograph. A passport works alone; otherwise, two items from the accepted list (foreign driver’s license, national ID card, foreign military ID, or foreign voter registration card) are required. Documents must be originals or notarized copies. Allow six weeks for verification; once approved, you’ll be told to complete the online application.⁸

One important limit: a PTIN obtained this way authorizes you to prepare returns only from outside the United States. It does not authorize you to prepare returns for compensation while physically in the U.S.⁸

Annual Renewal

Every PTIN expires on December 31. The renewal window opens in mid-October, and you must renew before preparing any returns for the next filing year.⁶ Missing December 31 doesn’t permanently revoke your number. You can still renew in January or later. But you cannot legally prepare returns for pay during the lapse.

Renewal is faster than the first application. Log into your existing PTIN account, and the system pre-fills your personal and professional details from the prior year. Review the information, update anything that’s changed, answer a short set of compliance questions, and pay the same $18.75 fee.⁹ Your renewed PTIN is active instantly.

If you let your PTIN lapse for multiple years, the IRS may assign you a new number rather than reactivate the old one. Once a new number is issued, your prior PTIN cannot be brought back; the new number goes on all returns going forward.⁶

What Holding a PTIN Obligates You to Do

Getting the number is the first step. Keeping it in good standing means meeting two ongoing obligations that catch some preparers off guard.

A Written Data Security Plan

Every PTIN holder is legally required to maintain a written data security plan protecting client information. During the application and each renewal, you’ll confirm that you know about this responsibility.¹ The IRS expects the plan to actually exist, not just the acknowledgment.

At minimum, the plan should:

Designate one or more employees to coordinate data security.
Identify where client data is stored, how it moves, and what could go wrong.
Implement safeguards such as encrypted storage, strong passwords, and locked files for paper records.
Require any outside vendor handling client data to contractually commit to appropriate security.
Get tested regularly and revised when circumstances change, including staff turnover.

Solo practitioners sometimes assume this rule applies only to larger firms. It doesn’t. A home-office preparer with a single client needs a security plan too.¹⁰

Circular 230 Conduct Standards

When you register or renew, you agree to follow Treasury Department Circular 230. That covers competence, diligence, conflicts of interest, fee practices, and how you communicate with the IRS on a client’s behalf.⁷ Violations are handled by the IRS Office of Professional Responsibility.

What Happens If You Prepare Returns Without a Valid PTIN

Preparing returns for pay without a valid PTIN carries real financial consequences. Under Internal Revenue Code Section 6695(c), the base penalty for failing to include your identifying number on a return is $50 per occurrence, capped at $25,000 per year.¹¹ Those base figures are adjusted for inflation each year. For returns filed in 2025, the adjusted penalty was $60 per return with a $31,500 annual cap.¹² Across even a small client base, that adds up quickly.

The penalty applies unless you can show reasonable cause, meaning an honest mistake rather than willful neglect. Simply forgetting to renew is difficult to argue as reasonable cause when the IRS provides a two-and-a-half-month renewal window each year.

Beyond per-return fines, the Office of Professional Responsibility can investigate Circular 230 violations. Discipline ranges from a formal reprimand to suspension or permanent revocation of the right to practice before the IRS.⁷ In the most serious cases, such as using a false PTIN, using someone else’s PTIN, or continuing to prepare returns after being told to stop, the IRS can seek a federal court injunction barring you from preparing returns and may pursue criminal charges alongside the civil penalties.
